TO ALL WHOM IT MAY CONOERN:

Be it known that I, GEORGE J. SWINGLE, of Knoxville, in the county of Knox,rand State of Illinois, have invented a new and useful Improvement in Fly-Traps; and I do hereby'declare that 'the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a side elevation.

Figure 2 is a longitudinal vertical section, as indicated by the line :r y in iig. 4.

Figure 3 is a side view in detail of trap-cover. I

Figure 4: is a top view.

Like letters in the different igures of the drawings indicate like parts.

This invention consists in the employment of a wire-cloth ily-receptacle or prison, two revolving feed or bait-rollers, clock-macliinery to impart the requisite motion to the device, a drowning-pan, andl a chimneydecoy, arranged substantially as hereinafter described, whereby an extremely eilicient article is obtained for the intended purpose. I v

To enable any one skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A represents a wirelcloth cylinder,.closed at either end, which is designed as a receptacle for such flies as escape the drowning-pan, and with this view it tits over or covers the illy-chimney, leading into this receptacleor prison. Within this cylinder, and near the apex oth-the aforesaid chimney, isV a gauze door, t', which rests and works upon a horizontal bar, to which it is attached, and which is designed, when closed, to prevent the egress of the iies', Y it being closed when it is desirable to removeit or to clean it out, by burning or drowning the dies. The ring a, which sui-mounts said cylinder, is designed to facilitate its removal and conveyance.

B is the trap-cover, which projects and opens up into the prison or receptacle A. It is surmounted with a chimney-shaped gangway, from whose apex projects the sharp prongs X, which 4debar the egress of the tlies. Attached to this trap-cover is the cloth screen b, which prevents the ilies from being startled by the trap.

C is a trap-door, fashioned after the manner of 'a hinge, whose doors or lids are elevated or lifted by the projectings prongs Z, which of their. own weight fall freelyagain upon the horizontal rollers'when they have revolved beyond the prongs. f

D D represent two cylinder-shaped rollers, inade of wood or other-suitable material, Whose-axis penetrates and rests upon the standards y y; and attached to these rollers are two cog-Wheels, K K, the one revolving in the other, and upon these rollers are fastened narrow strips of cloth, horizontally, at short intervals, supplied or covered over with any suitable substance or material-that will attract flies, and having prongs, Z Z, thereon, at one end projecting over the cloth, which prongs lift the doors until the revolvingr rollers carry the dies too far within to admit of their escape. p A

E is a drowning-pan, with rims or flanges, which rest it upon the transverse bars o o, and into which the iies fall who fail to pass under the trap-doors C.

Suitable clock-machinery will be used, which is represented under the cover F, for protecting it from injury,

I and which, when wound up, is impelled by a spring, and revolves the feed-rollers and lifts the trap-doors.

The whole is supported by the dat standards Y Y, which are made preferably of metal.

The operation is as follows: The feed or bait-rollers are supplied with any suitable substance or material that will attract flies, and the device is wound up and set on a table or other desirable place, and the flies being attracted by the bait, are unwittinglyconveyed under thev cloth screen, andy upon seeing the light above them, immediately ily thitherward,1 until they land-in the receptacle or prison A; but should any fail to be startled by the darkness and the falling of the trap-door, they will inevitably be carried with the roller` under the trapdoor and into the pan E, which is lled nearly full of-soap-suds, which quickly destroys thorn. A transverse 'bar o1' rod, d, may be used between the rollers, so that as they y upward they will strike against it, and thus fall into the suds.

Having thus fully described my invention, what I claim therein as new, and desire to secure by Letters Patent, isf- Y The arrangement of the receptacle or prison'A, gauze door v, trap-cover B, with prongs X, cloth screens b b, trap-door C, rollers D D, with 'prongs or curved pins Z, rod d, pan E, and rods O O, the whole combined and operating substantially in the manner and for the purpose as herein set forth.

GEORGE J. SWINGLE.
